I’ve been playing with fast-rcnn for a while. This amazing and wonderful project helps me understand more about deep learning and its beautiful power. However, there’s only a pre-trained fast rcnn model for pascal voc with 20 classes. To use this project in real applications, I need to train a model on the ImageNet detection dataset( For time’s sake, I only chose two classes out of 200 classes). So this blog records what to be done to train a fast rcnn on ImangeNet.
